ATTAC-HING DEVICE FoR DRILL-BRACES.

SPECIFICATION forming 'part of Letters Patent No. 690,669, dated January7, 1902.

Application filed J'ul'13| 1901.

To @ZZ iii/tom it may] cm1/cern:

Be it known that I,.To`HN F. STECKENRELTER,

of Chicago, in the county of Cook and State reaming holes in structuraliron, such as beams, round or square columns, chords of bridges,angle-bars, track-rails, and for like purposes.

Among the objects of the invention is to produce a device of thecharacter mentioned, which can be readily set in place and removedtherefrom, which is light and may be easily carried, and when once setin any position makes it possible to drill or rea'm holes in the part towhich it is attached in position at right angles to each other withoutthe necessity of changing the location of the device. j

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out inthe appended claims.

In the drawings, Figure l is an end elevay tion of an attaching devicemade in accord- 4ance with my invention, showing a drill stand- -ard orbrace attached thereto, said device being shown in position onA aT-beam. Fig. 2 is a side elevation of the device. Fig. 3 is a ,top planview thereof.. Fig. 4 illustrates a modification of the device, which isdesigned for use on angular columns, bridge-chords, or the like. Figs. 5and 6 illustrate modiiied means of attaching the device to a part to beoperated upon. Y

First referring to the construction shown in Figs. lto 3, inclusive, Adesignates as ya whole an attaching-base,consisting of a socket member Aand an angle member A2, both made of castmetal,preferably cast-steel.The socket member is provided with two sockets AB A4, adapted to receivethe standard B of the brace, which standard carries at its outer end aradial arm C, adapted to support the.

outer end of the ratchet-drill'. Said arm Cis saisi No. 62,848. (Nomodas herein shown,l at right angles, although the angle of intersectionmay vary. Said sockets,

as herein shown, pass entirely through the castings. D D designatehook-bolts, which pass through the base of the socket member A and areadapted to hook over the margin of the flange E of the beam E. Thelanglepiece A2 is formed to embrace the opposite Vmargin of the flange ofsaid beam and is lprovided with set-screws D', which pass upwardlythrough said angle-piece and impinge against the lower surface of saidllange. The socket member and angle-piece are connected together bymeans of clamping-bolts F, said bolts aiording ,means by which the partsof the device are 'adj usted to beams of dierent sizes. In order toinsure a rigid connection between the angle-piece and socket member, thebolts are lprovided with a plurality of washers F', which fill thevspacebetween said parts and act to hold said parts when o nce adjusted at afixed distance with respect to each other. The device is adjusted withrespect to the size of the beam or other part on which it is to be usedby interposing the required number of washers F between the angle-pieceand socket member. When the device is to be attached to a beam, thehookbolts D are rotated ninety degrees from the position shown in Fig.l, and the set-screws D' having been adj usted to suit the thickness ofthe flange E of the beam the angle-piece A2Vis hooked over one edge ofthe flange and the device set flat on the top of the beam.

Thereafter the hook-bolts are turned in bolt, as shown in Fig. 1, andthe set-screws D.

IOO

are slightly out of contact with the lowerv face of the liiange, asshown in said figure. With this construction when the hook-bolts D areturned or rotatedninety degrees from the position shown the device maybe readily disengaged from the beam by slightly turning or rocking thesame in the direction of the ange with which the angle-piece A2 isengaged. A sufficient number of washers F are provided to entirely tillthe space between the angle-piece and socket member for the widest beamfor which the device is adapted, andin adjusting the device to narrowerbeams the washers not required for the adjustment may be placed on theclamping-bolts F outside the flange member A2,A said outer ends of thebolts serving as storage places for the washers. Vhen the device hasbeen attached to the beam in the manner described, the standard B mayoccupy either the vertical socket A4 or the lateral socket A3 and isheld in said sockets by means of set-screws a a passing through thesockets and impinging at their inner ends against the standard. When thestandard is in a vertical position, as shown in full lines in Fig. l,the arm thereof serves to support the ratchet-drill in position fordrilling or reaming holes in the iianges E on either side of thestandard. When it is desired to drill or ream holes in the web of thebeam, the standard is inserted into the lateral socket, as shown indotted lines in Fig. 1. The device may be readily slipped longitudinallyof the beam from one position to another by turning the hook-bolt Doutwardly and sliding the device along the beam. After reaching a newposition it is fixed rigidly in place by again turning the hook-boltinwardly.

In Fig. 4 I have shown my improvements as adapted for drilling andreaming holes in a column made up of a plurality of Z-bars. This form ofthe device may also be employed for drilling and reaming holes in thechords of bridges in floor-plates and like parts. The device in thisinstance consists of a socketpiece A', made like the socket-piece shownin Fig. l and provided with the intersecting sockets A3 A4 and withhook-bolts D, adapted to engage the margins of the flange of the beam.In place of the iiange-piece A2 one or more angle-straps G are employed,which are provided at their inner ends with rightangle portions g,through which the clampingbolts F are passed and are provided at theirouter ends with hooked portions g which pass over the outer margins ofthe flanges on the beams remote from the anges engaged by the hook-boltD. The clamping-bolts are in this construction shown as provided withthe spacing-washers F, whereby the device may be adjusted to columns,chords, or plates of varying widths. IVhen the standard B is in theposition shown in full lines, the drill may be supported for drilling orreaming holes in the side flanges of the Z-bars and when in the positionshown in dotted lines serves to support a drill when drilling or reamingholes in the Webs of said beams. The parts G obviously correspond infunctions to the anglepieces A2 of the construction previouslydescribed,difl`ering therefrom in shape to adapt the same to other uses.

I have shown in Figs. 5 and G two modifications of the deviceconstructed for drilling or reaming beams or the like of standard sizesand cross-section. In Fig. 5, I designates a socket member provided withintersecting sockets I I2. The standard B may in this instance beinserted into either end of the lateral socket I2. The device is held inplace by means of two or more hook-bolts D on either side of the base ofthe socket member. This form of device may be readily attached to anddetached from the beam, as it is only required in attaching the deviceto lay the same flat on the Iiange of the beam or the like in connectionwith Which it is nsed,with the hook-bolts D turned parallel to eachother and at right angles to the position shown in Fig. 5. Thereaftersaid bolts are turned inwardly toward each other and under the iiangesof the beam, which serves to rigidly secure the device thereto. In Fig.6 the socket member J is provided Witht wo sockets J J2, made like thatshown in Fig. 5, and is adapted to be attached to the beam by means ofan integral hook or flange j at one side thereof and one or morehook-bolts I) on `the other side. In this instance the set-screwD (shownin Fig. l) may be omitted from the hook-fiange j. Desirably in thisconstruction the flange will be made to tit loosely upon the margin ofthe flange of the beam in connection with which it is used, so that,when the hook-bolts are turned outwardly to detach the device from thebeam,sufficient space will be allowed between said parts to permit thedevice to be rocked upwardly slightly to disengage the parts from thebeam.

Obviously other means may be employed for attaching the duplex socketmembers to a beam or other part in connection with which it is to beused, and I do not Wish to be limited to the means herein shown for thispurpose. Moreover, the device may be employed for attaching other partsin place, and I do not wish to be limited to the adaptation hereinshown.

The device described is very simple in its construction, occupies butlittle room, and can be made very light, so as to be readily handled inand about a building or other structure in connection with which it isemployed.
